Disclaimer: This cache is not on a grave!
It is placed in the church yard of St Mary's Church (Bletchley)
This church is a 13th century church. It really is a stunning building. Come and sit awhile and take a break from the busyness of life. Ponder the many lives that have gone through this building.
Avoid the muggles on a Sunday at 8am or 10am. (These are the service times)
(I happen to work for the church, so I did get permission to hide the cache there.)
(PS. It is not and never has been attached to a string...)
